Use foil method (8a - 8)(4a + 1)
BlackZzzverrR [31]
The answer is:  " 32a² − 24a − 8 " .
__________________________________________________
Given:
__________________________________________________
(8a − 8)(4a + 1) ;  Let us expand this expression using the:  "FOIL" method.
___________________________________________________
"FOIL" stands for "<u>F</u>irst terms, <u>O</u>uter terms, <u> I</u>nner Terms, <u>L</u>ast Terms" ;
           in that order.
___________________________________________________
Basically:
_______________________________________________________
(a + b)(c + d) = ac + ad + bc + bd ;

in which the:

<u>F</u>irst term is:    "ac" ;
<u>O</u>uter term is:  "ad" ;
<u>I </u>nner term is:   "bc" ;
<u>L</u>ast term is:    "bd " .
__________________________________
So; we have (given):

(8a − 8)(4a + 1) ;
__________________________________________________
Let's take the "<u>F</u>irst, <u>O</u>uter, <u> </u><u>I</u>nner, and <u>L</u>ast terms" ; as follows:
__________________________________________________
<u>F</u>:  (8a)*(4a) = 32a² ;
__________________________________________________
<u>O</u>:  (8a)*(1) = 8a ;
__________________________________________________
<u>I </u>:   (-8)*(4a) = -32a ;
__________________________________________________
<u>L</u>:  (-8)*(1) = -8
__________________________________________________
Now, let us write out these terms:
__________________________________________________
  32a² + 8a − 32a - 8 ;
__________________________________________________
Now, combine the "like terms" in this expression; to simplify:

       + 8a − 32a = -24a ;
__________________________________________________
and rewrite the simplified expression ; which is:
__________________________________________________
        32a² − 24a − 8 .
